GEORGE HASECOSTER, OF RICHMOND, INDIANA.

IMPROVEMENT IN LOOIviS FOR WEVING SLATTED WINDOW-SHADES.

Speciication forming part of Letters Patent No. 57,@98, dated September11, 1866.

To all whom it may concern:

Be it known that I, GEQRGE HASEGOSTER, ot' Richmond, Indiana, haveinvented a new and Improved Loom for XVeaving indow- Shades; and I dohereby declare the following to be a full and exact description thereof,reference being had to the accom panying drawings, and to the letters ofreference marked thereon.

The nature of my invention consists in suitable devices for delivering`the slat to be woven into a window-shade in its proper position withinthe shed of the warp, the same to be operated with the other mechanismot' the loom.

To enable those skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

In the drawings, Plate l is a perspective view of the front of the loom,and Plate2 is a perspective view, showing the back of my said loom.

In Plate l, A is a foot-board, vibrating; upon a suitable shaft, to theend of which is at- Y tached the pitman B, which revolves thedriving-wheel'b. On the opposite end of the shaft which supportsthe'driving-wheel is a pinion whichoperates the spur-wheel I), which inits turn operates the wheels E and F. The wheel I is placed upon asuitable shat't, upon the opposite end ot' which is the bevel-wheel G,said shaft having its bearings upon the framin The smaller bevel-wheel Hand the bevelwheel J are attached to opposite ends ot' the shaft I,which is placed at right angles to the shaft carrying the wheels G andIt', having its bearing upon a cross-framing, I'. rIhe bevelwheels K K'are at the ends of the shaft J', and are operated by the bevel-wheel J.The slide-rod L is attached to a sliding clutch, L', which is thrown ingear with` either ot' the wheels K K' as it is actuated by the lever M,to which it is attached. The shat't J' is provided with a pulley, 8,outside ot' the bearing of said shaft upon the framing wx. rEhe shaft t'extends across the lower part of the rear end of the frame, and isprovided with a pinionwheel, E, which receives its motion from thespur-wheel D. The drum U, situated upon the shaft t', has a spiralgroove cut in its circumferential surface, in which a pin at the rearend of the lever M works, giving a vibrating motion laterally to saidlever, and serving to alternate the action of the sliding clutch L'. Ateither end of the shaft fi is attached arms Z Z', each provided wit-h apin, which operates the rocker-shafts 7i h', said shafts being providedwith springs to bring them back into position. rIhe arm Z' is attachedat one end to the shaft 0 but the arm Z is made twice as long as Z', andis attached at its center to the shaft, so thatthe arm extending back ofthe shaft, which arm is provided witha pin, will raise the lever Y ateach` revolution, thereby operating the levers P P', through the meansof which the pawl Q turns the wheel O on the take-up or curtain beam N,by means of' a weight on said lever Y, which may be graduated to exertany desired amount of power.

To the tops ot' the rocker-arms h 7L' are attached short arms, which arehinged to connecting-bars, the opposite ends ot' which are pivoted tothe hatten-posts a c'. These constitute the means for producing thevibratory movement ofthe batten and its attachments.

Surmounting the hatten-posts andlextend ing across the loom is'the reed,composed of strips of any suitable material ofa width equal to the spacerequired between the threads ot' warp in the curtain or window-shade tobe woven.

At the lower edge of the reed and parallel with it is the shaft d',having its bearings in the batteri-posts c c'. rIhis shaft is providedwith curved bearings d d d, which are designed to catch and hold theslats to be woven as they are delivered by the carrier. The shaft iskept in position by a spring attached to the shaft near its center,secured to the back side ot' the reed, and also by small cords at eitherend, which are secured to the batten-beam. As the batten inclinesforward in the process of beating up the slat, the operation of thespringinclines the curved bearings downward, so that the slat isdelivered in the shed of the warp horizontally or tlatwise in a propermanner.

Upon the shaft S, and near its center, is iixed a star-wheel, l, havingfour arms, upon each ot' which is a projecting pin, at right angles tothe face of'the arm, two of which project to the right and the other twoto the left. These projecting; pins operate in their revolutions thelever-bars W W', which are pivoted to the upright connecting-bars V V',which in turn operate the treadles.

From the forward end of the treadles extend the cords or wires g g', theripper portions of each of which are made forked, and are secured to thelower edges of the heddle-frames e c, which frames are provided withperforated bars, corresponding in number and space to the openingsbetween the slats o c of the reed.

The spool-rack j is provided with pins, in number equal to the number ofthreads 1n the 'warp to be woven, the warp to be drawn from thewarp-spools 7c le', each turning upon a suitable shaft, k2, at rightangles to the bar of the rack j. The warp-cylinder R is provided withfriction-straps l l', working in recessesat either end, said strapsbeing attached to the sill -x of the framing, and the force of thepressure eX erted upon the cylinder is increased or diminished bysliding` the bands m m up or down.

The springs p p' are attached to the upper part ofthe rocker-shafts hh', andproduce the return motion of the hatten. The pulley 8 on theouter end of the shaft L is recessed to receive the cords 7, which arecoiled right and left around the same, extending` thence vertically topulley 9 on Plate l and to pulley 10 on Plate 2, and, runninghorizontally on each side of the center bar, 3, are attached to theslat-carrier 1. The spring or catch 2 is pivoted across the forward endof the slat-carrier at right angles, and on the op posite end receives awire, which connects it with the slide 1l, having a stop, l2. The slatis taken from the slattrough 5, and one end ofthe slat is inserted inthe catch or spring 2, the slat lying edgewise upon the slat-rest 6.rlhe carrier is now moved forward until' the stop 12 strikes against aprojecting pin upon the framing x. Then the catch or spring 2 is opened,and the slat deposited in the curved lbearings d d d. At this point thelever M shifts the sliding clutch L', the pulley 8 is turned theopposite way, and the slat-carrier is carried back to its originalposition, where it rests until the batten has made its f'orward motionand returned.

The ratchet-wheel O2, Plate 1, is attached to the shaft of thecurtain-cylinder N, and upon the outside of the framing m is pivoted astoplever, O', which may be used to stop the action of the take-up atany desired point in case of any derangement in the operations of theloom.

Upon the shaft d' is a wing, 13, supported by a spring, and movable uponthe shaft, in-

tended to check the motion of the slat-carrie11 at the proper point, andcapable of being placed at the proper point for weaving curtains orblinds of different widths. The wing 14, at the opposite end of theshaft d', is intended to serve a like Purpose.

rI he spring l5, attached to the inner side of the framing a: at the endof the reed, is intended to hold the reed and hatten in place, andprevent any shaking or tremulous motion by which the shed or warp mightbe disturbed. The spring 16, interposed Ybetween `the cord 7 and theslat-carrier l, at its connection with the same, serves to compensatefor any sudden strain upon the cord 7 and prevent precipitate action inits motion.

The friction-roller N' is placed nearly above the curtain-cylinder N andserves to lessen friction on the curtain as it passes to thecurtain-cylinder N.

Having thus fully described my said improvement, what I claim as new,and desire to secure by Letters Patent, is-

1. The slat-trough 5 and slat-rest 6, in combination with theslat-carrier l, all arranged and operating as and for the purposes setforth and described.

2. The cord 7, spring 16, slide 1l, and stop l2, when so arranged andoperating as to carry and deliver the slats within the shed, incombination with slatcarrier 1, substantially as set forth.

3. The combination of the pulley 8, cord 7, and sliding clutch L', whenoperated as and for the purposes set forth.

4. The shaft i, pinion E, drum U, and arms Z and Z', arranged as and forthe purposes set forth.

5. The combination of the star-wheel T, levers W W', connections V V',and treadles t t, as set forth and described.

6. The shaft d' and its curved bearings d d d, constructed and operatingas herein set forth and described.

7. The combination of the hatten a a, reed o,.and shaft d', with itscurved bearings d d d, when arranged and operating as and for thepurposes set forth.
